Etymology : Acquiesce means essentially “to comply quietly,” so it should not surprise you to learn that it is ultimately derived from the Latin verb qui?scere, meaning “to be quiet.” It arrived in English in the early 1600s, via the French acquiescer, with the senses “to agree or comply” and “to rest satisfied” (this latter sense is now obsolete). An early example of the word acquiesce in the sense of “to agree or comply” can be found in the writings of the English philosopher Thomas Hobbes who, in his 1651 masterpiece, Leviathan, argued that people must subject themselves completely to a sovereign and should obey the teachings of the church. Encouraging his readers to adopt his position he wrote, “Our Beleefe … is in the Church; whose word we take, and acquiesce therein.”
